摘要

Abstract

During power grid cascading failure

the operating point changes frequently

resulting in a mismatch or inaccuracy of online pre-decision making emergency control strategy. To solve this problem

an online power system stability decisionmaking and control method based on super-real-time simulation is presented in this paper. A decision-making and control system is developed in which the three main operation modes

offline pre-decision-making

online pre-decision-making

and real-time control

are all coordinated. To verify the method

ADPSS (advanced digital power system simulator) is used to simulate a digital power grid with about 20

000 buses. The closed-loop operation of the digital power grid and the online decisionmaking and control system are implemented. Test results show that when online pre-decision making control strategies are mismatched

aided real-time control works well and can prevent power grid stability loss.
